Want this question answered?
3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
6n + 7n (= 13n)
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
If the question was: "What is the answer to 8 cows plus 4 cows ?", you'd have no trouble with it. Why are 'x's so much more mysterious and harder to handle than cows are ??
18 is a solution to the equation 4 plus 7 times a number where the result is 9 times that number.
3 times 3 = 9 plus the number 3 = 12.
How about: 1 times 91 plus 4 = 95 or 7 times 13 plus 4 = 95
the number is 3 because 3 times 5 is 15 plus 2 is 17
3
6n + 7n = 13n

3x+5x
6n + 7n (= 13n)
Because they are both multiples of two, so when they're added, the sum must be another multiple of two. (One group of twos plus another group of twos must be a new group of twos, just like one group of cows plus another group of cows must be a new group of cows.)
2 times a number minus 17 plus 20 times a number minus 9 is the same as 2x - 17 + 20x - 9 = 22x - 26
